(EN) Disclosed is a device for the sandblasting of even surfaces (18) wherein the sandblaster emerges in a regular manner from an outlet (9) extending over the entire width of the assemblage, thereby enabling a regular sandblasting effect to obtained. Furthermore, the requisite pressure differentials are lower than in conventional devices, since the outlet is led, at a close distance, past the surface which is to be sandblasted, thereby resulting in a reduction in the level of pressure required.
